| 摘要 |
The object of the present invention is to provide an electrode for secondary battery according to which the electrode density can be increased and furthermore the electric characteristics can be improved. In the present invention, the sheet material for electrode to be laminated on the surface of a current collector is prepared by mixing and kneading a powdered positive electrode active material or negative electrode active material and a finely powdered conductive material as main components to which a fluorine-containing polymer resin is added, screening the resulting mixture by a sieve to obtain particles of the mixture, adding a liquid lubricant to the particles, preforming the particles to make a sheet-like formed body, and stretching the sheet-like formed body in mono-axial or multi-axial direction.
